The Mundorf TubeCap is made of polyprophylene film with special features. This is particularly thin and the self healing properties are markedly pronounced, due to a special coating. This leads to a very high electrical strength in the capacitor with compact dimensions.

The TubeCap combines a high degree of dielectric strength and low residual inductivity with a very compact form of construction. It has been developed as a high-quality technical alternative to high-voltage electrolytic capacitors and is thus ideally suited to use in tube amplifiers.

As compared to electrolytics:

Lower ESR and lower residual inductivity.

No drying out; therefore longer service life.

Excellent self-healing properties.

More compact form of construction

No series connection necessary for increasing the dielectric strength.

Our precision matching applies to "pairs". You may request a larger matched group, but it may not be possible. NOTE: capacitors and precision matching are priced
and sold individually ("each"). Occasionally, we can not find a matched pair. If this is the case, Customer Service will contact you. We offer three levels of pair matching: L1-factory tolerance 1% matching; L2-1/2 factory tolerance 1% matching; L3-1/4 factory tolerance 1/2% matching.
